San Diego roofing is shaped by wildfire risk in the backcountry and eastern communities (El Cajon, Santee, Ramona, Lakeside, Poway) — all in VHFHSZ where Class A fire-rated materials are required. The 2003 Cedar Fire, 2007 Witch Creek Fire, and ongoing fire events make fire-rated roofing a real priority, not just a code requirement. SDG&E coordinates interconnection for solar-ready roofing in San Diego County. Title 24 cool roof requirements apply to all re-roofing. C-39 license required.
